Struct nannou::vk::SwapchainImage

pub struct SwapchainImage<W> { /* fields omitted */ }

An image that is part of a swapchain.

Creating a SwapchainImage is automatically done when creating a swapchain.

A swapchain image is special in the sense that it can only be used after being acquired by calling the acquire method on the swapchain. You have no way to know in advance which swapchain image is going to be acquired, so you should keep all of them alive.

After a swapchain image has been acquired, you are free to perform all the usual operations on it. When you are done you can then present the image (by calling the corresponding method on the swapchain), which will have the effect of showing the content of the image to the screen. Once an image has been presented, it can no longer be used unless it is acquired again.

Methods

impl<W> SwapchainImage<W>

pub unsafe fn from_raw(
    swapchain: Arc<Swapchain<W>>,
    id: usize
) -> Result<Arc<SwapchainImage<W>>, OomError>

Builds a SwapchainImage from raw components.

This is an internal method that you shouldn't call.

pub fn dimensions(&self) -> [u32; 2]

Returns the dimensions of the image.

A SwapchainImage is always two-dimensional.

pub fn swapchain(&self) -> &Arc<Swapchain<W>>

Returns the swapchain this image belongs to.

Trait Implementations

impl<W> ImageViewAccess for SwapchainImage<W>

fn parent(&self) -> &dyn ImageAccess

fn dimensions(&self) -> Dimensions

Returns the dimensions of the image view.

fn inner(&self) -> &UnsafeImageView

Returns the inner unsafe image view object used by this image view.

fn descriptor_set_storage_image_layout(&self) -> ImageLayout

Returns the image layout to use in a descriptor with the given subresource.

fn descriptor_set_combined_image_sampler_layout(&self) -> ImageLayout

Returns the image layout to use in a descriptor with the given subresource.

fn descriptor_set_sampled_image_layout(&self) -> ImageLayout

Returns the image layout to use in a descriptor with the given subresource.

fn descriptor_set_input_attachment_layout(&self) -> ImageLayout

Returns the image layout to use in a descriptor with the given subresource.

fn identity_swizzle(&self) -> bool

Returns true if the view doesn't use components swizzling.

fn format(&self) -> Format

Returns the format of this view. This can be different from the parent's format.

fn samples(&self) -> u32

fn can_be_sampled(&self, _sampler: &Sampler) -> bool

Returns true if the given sampler can be used with this image view.

impl<W> ImageClearValue<<Format as FormatDesc>::ClearValue> for SwapchainImage<W>

fn decode(
    &self,
    value: <Format as FormatDesc>::ClearValue
) -> Option<ClearValue>

impl<W> ImageAccess for SwapchainImage<W>

fn inner(&self) -> ImageInner

Returns the inner unsafe image object used by this image.

fn initial_layout_requirement(&self) -> ImageLayout

Returns the layout that the image has when it is first used in a primary command buffer.

fn final_layout_requirement(&self) -> ImageLayout

Returns the layout that the image must be returned to before the end of the command buffer.

fn conflicts_buffer(&self, other: &dyn BufferAccess) -> bool

Returns true if an access to self potentially overlaps the same memory as an access to other.

fn conflicts_image(&self, other: &dyn ImageAccess) -> bool

Returns true if an access to self potentially overlaps the same memory as an access to other.

fn conflict_key(&self) -> u64

Returns a key that uniquely identifies the memory content of the image. Two ranges that potentially overlap in memory must return the same key.

fn try_gpu_lock(&self, bool, ImageLayout) -> Result<(), AccessError>

Locks the resource for usage on the GPU. Returns an error if the lock can't be acquired.

unsafe fn layout_initialized(&self)

When images are created their memory layout is initially Undefined or Preinitialized. This method allows the image memory barrier creation process to signal when an image has been transitioned out of its initial Undefined or Preinitialized state. This allows vulkano to avoid creating unnecessary image memory barriers between future uses of the image.

fn is_layout_initialized(&self) -> bool

unsafe fn increase_gpu_lock(&self)

Locks the resource for usage on the GPU. Supposes that the resource is already locked, and simply increases the lock by one.

unsafe fn unlock(&self, Option<ImageLayout>)

Unlocks the resource previously acquired with try_gpu_lock or increase_gpu_lock.

fn format(&self) -> Format

Returns the format of this image.

fn has_color(&self) -> bool

Returns true if the image is a color image.

fn has_depth(&self) -> bool

Returns true if the image has a depth component. In other words, if it is a depth or a depth-stencil format.

fn has_stencil(&self) -> bool

Returns true if the image has a stencil component. In other words, if it is a stencil or a depth-stencil format.

fn mipmap_levels(&self) -> u32

Returns the number of mipmap levels of this image.

fn samples(&self) -> u32

Returns the number of samples of this image.

fn dimensions(&self) -> ImageDimensions

Returns the dimensions of the image.

fn supports_blit_source(&self) -> bool

Returns true if the image can be used as a source for blits.

fn supports_blit_destination(&self) -> bool

Returns true if the image can be used as a destination for blits.

unsafe fn preinitialized_layout(&self) -> bool

unsafe fn forced_undefined_initial_layout(
    self,
    preinitialized: bool
) -> ImageAccessFromUndefinedLayout<Self>

Wraps around this ImageAccess and returns an identical ImageAccess but whose initial layout requirement is either Undefined or Preinitialized.

impl<P, W> ImageContent<P> for SwapchainImage<W>

fn matches_format(&self) -> bool

Checks whether pixels of type P match the format of the image.
